Arknights: Building and Using the Alter Caster Guide

As the first "Alter" Operator in Arknights, Lava the Purgatory is not just an enhanced version of her original form; she's a formidable 5-star Splash Caster who offers both team utility and remarkable versatility. Whether you're leveraging her for widespread AoE damage or enhancing the performance of other Casters, she proves to be a dependable asset in a variety of team compositions.

Unlike many damage-focused characters in this tactical game, Lava the Purgatory supports her allies while dishing out potent area Arts attacks. Equipped with two effective skills and a standout talent that accelerates SP generation for your entire Caster team, she's an excellent choice for more than just specialized scenarios. Let's delve deeper into her capabilities and how to optimize her build.

Operator Overview

Lava the Purgatory is a 5-star Splash Caster renowned for her ability to deliver AoE Arts damage across a broad area. As with all Splash Casters, her attacks affect multiple tiles simultaneously and are particularly effective against enemies with low to moderate RES. What sets her apart is her talent that fosters synergy and her second skill, which significantly alters her tactical approach.

Introduced as a welfare Operator during the Who is Real event, she can be permanently unlocked via Record Restoration. Unlike the original Lava, this version boasts superior stats, access to Elite 2, and more intricate gameplay mechanics. While she shares Trust with her original counterpart, her upgrades, potentials, and skills are entirely distinct.

Talents: Spell Formation and SP Support

In the realm of Arknights' combat, Lava the Purgatory's primary utility stems from her talent, Spell Formation. This talent grants her immediate SP upon deployment and shares SP with other Casters on the field or when they are deployed. The SP values increase with her promotion level; at Elite 2, she gains 30 SP upon deployment and provides an additional +4 SP to all Casters each time she's deployed.

She synergizes well with frontline defenders and medics. Her skill, Ring of Hellfire, protects defenders by inflicting burn damage on nearby enemies, making her an excellent choice for teams focused on lane control or stall tactics.

Some effective synergy options include:

• Eyjafjalla or Ceobe: For an SP boost and combined AoE damage
• Saria or Nearl: Healers who can withstand damage while Lava burns surrounding enemies
• Other Splash Casters: Goldenglow and Skyfire benefit from faster skill cycles

Lava the Purgatory is a highly refined alter Operator who seamlessly integrates AoE damage, utility, and team support. She's user-friendly for early game content due to her consistent splash damage, yet offers deep strategic value with her SP-boosting talent and area control skill. Whether you're running a caster-heavy lineup or simply need an AoE burn field around your defenders, she brings substantial value to your team.

To fully harness her ranged capabilities and enhance visual clarity, consider playing Arknights on PC with BlueStacks. This setup provides a broader view of the battlefield, faster controls, and smoother performance—perfect for precisely positioning skills like Ring of Hellfire.
